## 快速开始
|
|||
|
|
|||
|
如下,引入当前包就可以快速的使用
|
|||
|
|
|||
|
```go
|
|||
|
package main
|
|||
|
|
|||
|
import (
|
|||
|
"fmt"
|
|||
|
|
|||
|
"github.com/gookit/color"
|
|||
|
)
|
|||
|
|
|||
|
func main() {
|
|||
|
// 简单快速的使用,跟 fmt.Print* 类似
|
|||
|
color.Redp("Simple to use color")
|
|||
|
color.Redln("Simple to use color")
|
|||
|
color.Greenp("Simple to use color\n")
|
|||
|
color.Cyanln("Simple to use color")
|
|||
|
color.Yellowln("Simple to use color")
|
|||
|
|
|||
|
// 简单快速的使用,跟 fmt.Print* 类似
|
|||
|
color.Red.Println("Simple to use color")
|
|||
|
color.Green.Print("Simple to use color\n")
|
|||
|
color.Cyan.Printf("Simple to use %s\n", "color")
|
|||
|
color.Yellow.Printf("Simple to use %s\n", "color")
|
|||
|
|
|||
|
// use like func
|
|||
|
red := color.FgRed.Render
|
|||
|
green := color.FgGreen.Render
|
|||
|
fmt.Printf("%s line %s library\n", red("Command"), green("color"))
|
|||
|
|
|||
|
// 自定义颜色
|
|||
|
color.New(color.FgWhite, color.BgBlack).Println("custom color style")
|
|||
|
|
|||
|
// 也可以:
|
|||
|
color.Style{color.FgCyan, color.OpBold}.Println("custom color style")
|
|||
|
|
|||
|
// internal style:
|
|||
|
color.Info.Println("message")
|
|||
|
color.Warn.Println("message")
|
|||
|
color.Error.Println("message")
|
|||
|
|
|||
|
// 使用内置颜色标签
|
|||
|
color.Print("<suc>he</><comment>llo</>, <cyan>wel</><red>come</>\n")
|
|||
|
// 自定义标签: 支持使用16色彩名称,256色彩值,rgb色彩值以及hex色彩值
|
|||
|
color.Println("<fg=11aa23>he</><bg=120,35,156>llo</>, <fg=167;bg=232>wel</><fg=red>come</>")
|
|||
|
|
|||
|
// apply a style tag
|
|||
|
color.Tag("info").Println("info style text")
|
|||
|
|
|||
|
// prompt message
|
|||
|
color.Info.Prompt("prompt style message")
|
|||
|
color.Warn.Prompt("prompt style message")
|
|||
|
|
|||
|
// tips message
|
|||
|
color.Info.Tips("tips style message")
|
|||
|
color.Warn.Tips("tips style message")
|
|||
|
}
|
|||
|
```
|
|||
|
|
|||
|
> 运行 demo: `go run ./_examples/demo.go`

|
|
|||
|
## 基础颜色(16-color)
|
|||
|
|
|||
|
提供通用的API方法:`Print` `Printf` `Println` `Sprint` `Sprintf`
|
|||
|
|
|||
|
> 支持在windows `cmd.exe` `powerShell` 等终端使用
|
|||
|
|
|||
|
```go
|
|||
|
color.Bold.Println("bold message")
|
|||
|
color.Black.Println("bold message")
|
|||
|
color.White.Println("bold message")
|
|||
|
color.Gray.Println("bold message")
|
|||
|
color.Red.Println("yellow message")
|
|||
|
color.Blue.Println("yellow message")
|
|||
|
color.Cyan.Println("yellow message")
|
|||
|
color.Yellow.Println("yellow message")
|
|||
|
color.Magenta.Println("yellow message")
|
|||
|
|
|||
|
// Only use foreground color
|
|||
|
color.FgCyan.Printf("Simple to use %s\n", "color")
|
|||
|
// Only use background color
|
|||
|
color.BgRed.Printf("Simple to use %s\n", "color")
|
|||
|
```
|
|||
|
|
|||
|
> 运行demo: `go run ./_examples/color_16.go`
|
|||
|
|
|||
|
![basic-color](_examples/images/basic-color.png)
|
|||
|
|
|||
|
### 构建风格
|
|||
|
|
|||
|
```go
|
|||
|
// 仅设置前景色
|
|||
|
color.FgCyan.Printf("Simple to use %s\n", "color")
|
|||
|
// 仅设置背景色
|
|||
|
color.BgRed.Printf("Simple to use %s\n", "color")
|
|||
|
|
|||
|
// 完全自定义: 前景色 背景色 选项
|
|||
|
style := color.New(color.FgWhite, color.BgBlack, color.OpBold)
|
|||
|
style.Println("custom color style")
|
|||
|
|
|||
|
// 也可以:
|
|||
|
color.Style{color.FgCyan, color.OpBold}.Println("custom color style")
|
|||
|
```
|
|||
|
|
|||
|
直接设置控制台属性:
|
|||
|
|
|||
|
```go
|
|||
|
// 设置console颜色
|
|||
|
color.Set(color.FgCyan)
|
|||
|
|
|||
|
// 输出信息
|
|||
|
fmt.Print("message")
|
|||
|
|
|||
|
// 重置console颜色
|
|||
|
color.Reset()
|
|||
|
```
|
|||
|
|
|||
|
> 当然,color已经内置丰富的色彩风格支持
|
|||
|
|
|||
|
### 扩展风格方法
|
|||
|
|

|
|||
|
## 256 色彩使用
|
|||
|
|
|||
|
> 256色彩在 `v1.2.4` 后支持Windows CMD,PowerShell 环境
|
|||
|
|
|||
|
### 使用前景或后景色
|
|||
|
|
|||
|
- `color.C256(val uint8, isBg ...bool) Color256`
|
|||
|
|
|||
|
```go
|
|||
|
c := color.C256(132) // fg color
|
|||
|
c.Println("message")
|
|||
|
c.Printf("format %s", "message")
|
|||
|
|
|||
|
c := color.C256(132, true) // bg color
|
|||
|
c.Println("message")
|
|||
|
c.Printf("format %s", "message")
|
|||
|
```
|
|||
|
|
|||
|
### 使用256 色彩风格
|
|||
|
|
|||
|
> 可同时设置前景和背景色
|
|||
|
|
|||
|
- `color.S256(fgAndBg ...uint8) *Style256`
|
|||
|
|
|||
|
```go
|
|||
|
s := color.S256(32, 203)
|
|||
|
s.Println("message")
|
|||
|
s.Printf("format %s", "message")
|
|||
|
```
|
|||
|
|
|||
|
可以同时添加选项设置:
|
|||
|
|
|||
|
```go
|
|||
|
s := color.S256(32, 203)
|
|||
|
s.SetOpts(color.Opts{color.OpBold})
|
|||
|
|
|||
|
s.Println("style with options")
|
|||
|
s.Printf("style with %s\n", "options")
|
|||
|
```
|
|||
|
|
|||
|
> 运行 demo: `go run ./_examples/color_256.go`
|
|||
|
|
|||
|
![color-tags](_examples/images/color-256.png)
|
|||
|
|
|||
|
## RGB/True色彩使用
|
|||
|
|
|||
|
> RGB色彩在 `v1.2.4` 后支持 Windows `CMD`, `PowerShell` 环境
|
|||
|
|
|||
|
**效果预览:**
|
|||
|
|
|||
|
> 运行 demo: `Run demo: go run ./_examples/color_rgb.go`
|
|||
|
|
|||
|
![color-rgb](_examples/images/color-rgb.png)
|
|||
|
|
|||
|
代码示例:
|
|||
|
|
|||
|
```go
|
|||
|
color.RGB(30, 144, 255).Println("message. use RGB number")
|
|||
|
|
|||
|
color.HEX("#1976D2").Println("blue-darken")
|
|||
|
color.HEX("#D50000", true).Println("red-accent. use HEX style")
|
|||
|
|
|||
|
color.RGBStyleFromString("213,0,0").Println("red-accent. use RGB number")
|
|||
|
color.HEXStyle("eee", "D50000").Println("deep-purple color")
|
|||
|
```
|
|||
|
|
|||
|
### 使用前景或后景色
|
|||
|
|
|||
|
- `color.RGB(r, g, b uint8, isBg ...bool) RGBColor`
|
|||
|
|
|||
|
```go
|
|||
|
c := color.RGB(30,144,255) // fg color
|
|||
|
c.Println("message")
|
|||
|
c.Printf("format %s", "message")
|
|||
|
|
|||
|
c := color.RGB(30,144,255, true) // bg color
|
|||
|
c.Println("message")
|
|||
|
c.Printf("format %s", "message")
|
|||
|
```
|
|||
|
|
|||
|
- `color.HEX(hex string, isBg ...bool) RGBColor` 从16进制颜色创建
|
|||
|
|
|||
|
```go
|
|||
|
c := color.HEX("ccc") // 也可以写为: "cccccc" "#cccccc"
|
|||
|
c.Println("message")
|
|||
|
c.Printf("format %s", "message")
|
|||
|
|
|||
|
c = color.HEX("aabbcc", true) // as bg color
|
|||
|
c.Println("message")
|
|||
|
c.Printf("format %s", "message")
|
|||
|
```
|
|||
|
|
|||
|
### 使用RGB风格
|
|||
|
|
|||
|
> 可同时设置前景和背景色
|
|||
|
|
|||
|
- `color.NewRGBStyle(fg RGBColor, bg ...RGBColor) *RGBStyle`
|
|||
|
|
|||
|
```go
|
|||
|
s := color.NewRGBStyle(RGB(20, 144, 234), RGB(234, 78, 23))
|
|||
|
s.Println("message")
|
|||
|
s.Printf("format %s", "message")
|
|||
|
```
|
|||
|
|
|||
|
- `color.HEXStyle(fg string, bg ...string) *RGBStyle` 从16进制颜色创建
|
|||
|
|
|||
|
```go
|
|||
|
s := color.HEXStyle("11aa23", "eee")
|
|||
|
s.Println("message")
|
|||
|
s.Printf("format %s", "message")
|
|||
|
```
|
|||
|
|
|||
|
- 可以同时添加选项设置:
|
|||
|
|
|||
|
```go
|
|||
|
s := color.HEXStyle("11aa23", "eee")
|
|||
|
s.SetOpts(color.Opts{color.OpBold})
|
|||
|
|
|||
|
s.Println("style with options")
|
|||
|
s.Printf("style with %s\n", "options")
|
|||
|
```
|
|||
|
|
|||
|
## 使用颜色标签
|
|||
|
|
|||
|
> **支持** 在windows `cmd.exe` `PowerShell` 使用
|
|||
|
|
|||
|
使用内置的颜色标签,可以非常方便简单的构建自己需要的任何格式
|
|||
|
|
|||
|
> 同时支持自定义颜色属性: 支持使用16色彩名称,256色彩值,rgb色彩值以及hex色彩值
|
|||
|
|
|||
|
```go
|
|||
|
// 使用内置的 color tag
|
|||
|
color.Print("<suc>he</><comment>llo</>, <cyan>wel</><red>come</>")
|
|||
|
color.Println("<suc>hello</>")
|
|||
|
color.Println("<error>hello</>")
|
|||
|
color.Println("<warning>hello</>")
|
|||
|
|
|||
|
// 自定义颜色属性
|
|||
|
color.Print("<fg=yellow;bg=black;op=underscore;>hello, welcome</>\n")
|
|||
|
|
|||
|
// 自定义颜色属性: 支持使用16色彩名称,256色彩值,rgb色彩值以及hex色彩值
|
|||
|
color.Println("<fg=11aa23>he</><bg=120,35,156>llo</>, <fg=167;bg=232>wel</><fg=red>come</>")
|
|||
|
```
|
|||
|
|
|||
|
- 使用 `color.Tag`
|
|||
|
|
|||
|
给后面输出的文本信息加上给定的颜色风格标签
|
|||
|
|
|||
|
```go
|
|||
|
// set a style tag
|
|||
|
color.Tag("info").Print("info style text")
|
|||
|
color.Tag("info").Printf("%s style text", "info")
|
|||
|
color.Tag("info").Println("info style text")
|
|||
|
```
|
|||
|
|
|||
|
> 运行 demo: `go run ./_examples/color_tag.go`

|||
|
|
|||
|

## 颜色转换
|
|||
|
|
|||
|
支持 Rgb, 256, 16 色彩之间的互相转换 `Rgb <=> 256 <=> 16`
|
|||
|
|
|||
|
```go
|
|||
|
basic := color.Red
|
|||
|
basic.Println("basic color")
|
|||
|
|
|||
|
c256 := color.Red.C256()
|
|||
|
c256.Println("256 color")
|
|||
|
c256.C16().Println("basic color")
|
|||
|
|
|||
|
rgb := color.Red.RGB()
|
|||
|
rgb.Println("rgb color")
|
|||
|
rgb.C256().Println("256 color")
|
|||
|
```
|
